Abstract Cortical activity results from the interplay between network-connected regions that integrate information and stimulus-driven processes originating from sensory motor networks responding to specific tasks. Separating the information due to each of these components has been challenging, and the relationship as measured by fMRI in each of these cases Rest (network) and Task (stimulus driven) remains a significant outstanding question in the study of large-scale brain dynamics.

Abstract Ongoing cortical activity is shaped by the interactions between brain regions connected on a macroscopic level. While components of the activity reflect specific processes responding to a presented stimulus, the vast majority persists as a background activity that innately exists due to cortical loops present in the connectivity.
